Jigan and Jizhao: The Convergence of Yi Learning of Song Dynasty and Sinicized Buddhism

Jigan (寂感), derived from the Book of Changes, which states “when remaining in serene stillness without stirring, it attains universal penetration once stirred by resonance (jiran budong ganer suitong 寂然不動感而遂通).” It describes the profound subtlety of the Zhouyi. On the other hand, Jizhao (寂照) is a Sinicized Buddhist interpretation denoting the non-dual integration of true suchness and prajñā wisdom. Jigan developed into an ontological framework during the Song Dynasty (960–1279), while jizhao took shape during the Wei-Jin period. Philosophically, both manifest a non-dual substance-function structure “quiescence as resonance” and “quiescence as illumination.” They jointly serve as the foundational model for mind-nature cultivation and spiritual transcendence. From this theory of cultivation, however, divergent spiritual aspirations of Confucianism and Buddhism. Confucianism elucidates the principle of universal oneness of all things through quietude-resonance, pursuing the spiritual realm of sagehood. By contrast, Buddhism penetrates through self-attachment and dharma-attachment via quiescent illumination, thereby detaching from all karmic conditions, and manifests Prajñā. Confucianism integrates the practice of jigan into its ritual education, sacrificial ceremonies and daily disciplinary norms, rendering it a practical pathway for sustaining the cosmic-ethical order and generating ritual authority. Buddhism implements jizhao in meditation, precepts, and monastic life, constructing an enlightenment-oriented sacred community. Jigan and jizhao represent two distinct paths of religious transformation and spiritual attainment. This paper compares how both emanate from the ontological state of “serene stillness without stirring” into practical cultivation manifested as “resonance penetrating all things” or “simultaneity of illumination and function”, and ultimately shape divergent modes of sacredness and forms of social integration. While jigan and jizhao reveal a structural convergence in the cultivation theories of Confucianism and Buddhism, they also demonstrate disparate orientations in their spiritual aspirations.
